SPECIAL FEATURES
Interface escape character
Many of the features described in this chapter are accessed by
means of escape sequences. To gain access to these features you
must define an interface escape character. The first character of
all escape sequences is always a special character called the
interface escape character. You may define this character by
sending the following character sequence from the host:
&&??
E
Where 
E
 is the single character which is used as the interface
escape character and must be in the range X'40' to X'FF'. If a
value of X'40' (space character) is used, then the current interface
escape character is reset and no interface escape character is
defined. For example, to define the interface escape character as
'@', the following sequence must be sent:
&&??@
The interface escape character for the remainder of this chapter
is '@'.
Notes:
1. You should reset the interface escape character when you are
not using the XCTO’s special features.
2. XCTO does not pass the interface escape character.
Therefore, both the interface and the printer escape character
must be different. Only the interface escape character is
covered in this document.  For details of the Xerox Escape
Sequence (XES) printer escape character, see the Xerox 4213
Laser Printing System Printer Programmer Reference.
Format of escape sequences
Valid escape sequences must be in one of the following formats:
1. @Y..........@
Example:
Downloading set up parameters
2. @HH
where HH is a transparent HEX code
Example:
Single byte transparency
3. @Tn,
where n is the number 1 or 2
Example:
Print translate table
